as well as连接两个动词时,有三种情况：
1）前后两个动词的时态要一致.即：若第一个动词是一般现在时,第二个动词也应是一般现在时；若第一个动词是一般过去时,第二个动词也应是一般过去时.例如：
He publishes（published）as well as prints（printed）his own books．他的书是自己印刷并出版的.
2）如果第一个动词是复合时态,或由can,may,must等加动词构成时,as well as后面可省去助动词或情态动词,此时,as well as意为“既……又……”.例如：
We are repairing the roof as well as painting the walls．我们在粉刷墙壁,同时也在修理屋顶.
She can ／could sing as well as dance．她既会跳舞也会唱歌.
3）如果第一个动词是不定式,as well as后面的动词也要用不定式,但要去掉to.例如：
You can't expect her to do the housework as well as look after the children．你不可能叫她既照管孩子又做家务.
